y i Appiicaaon mea August 12,1908. seria'i No. 448,132.

To all. whomit may concern:

Be it known lthatI, ALLEN R. GriLiiiOiin, a citizen'of the United States of America, re-

' siding in the countyfoi' St. Lo'uis'A and State of.

Missouri, have invented certain new and use-v yful Im' rvements in Flushing-Tanks, of wlncht efol-lowingris a l'ull, clear, and exact description, reference being had tothe accompanying drawings, forming part .of this 1.0 .v A y.

Speolcation- My invention 'relates to a water closet tlushngtank and lit has for its object the furnishing of' means in connection with the float 'valvethat controls the ingress of Water into the Hush pipe, whereby said valve is'balanced -When-it is unseated in order that it will remain in an elevated position-until the tank has-been emptied in closet flushing action and Willbe-permitted to return in a positive manner ,to'itsflush ipe controlling position as soon as the tank as become emptied.

I -Figure I is a vertical longitudinal section taken through my flushing tank. Fig. Il is an'enlarg'ed topv or plan View of the countervbalance lever that controls the iiush valve V Fig. III is a cross sec'tion'taken on line III-Ill, Fig. 1I. Fig.

` IV is an enlarged vertical `section through the 'Hush valve. In the accompanying drawings, l designates a tanl or cistern that may bc of any desiredconstruction.

21s a Hush pipe connection mounted in the ftan'k 1 and provided interiorly oi' said tank f with a' valve seat member 3 through which water may beI discharged into the [lush pipe (notsliown): The llush pipe connection -is provided with a hollow lateral extension4 to which is attached the vertical overilow pipe 5 lthat isprovided at its upper'end with a float valve 6.

'A designates a flush valve that comprises a float 7 which is referabiy ol' tubular form and provided wit i an open lower end and a valve seat member S surrounding said Hoet, said valve seat member beingr preferably of rubber. The llush valve A is connected to a lift rod 9 that is operable in a guide 1() supported by the overflow pi e 5. l

1-1 designates a counter alance lever that is p-ivotaltliy connect-ed at its inner end to the upper en of the lift rod 9 and is provided at its outer end with a counterbalance 12. The counterbalance lever is pivotally sup- 'ported intermediate of its ends by a bracket 13 secured to the tank 1. The counterbalance 12 is of such Weight as to cause it to serve as a balance for the inner arm o1' the counterbalance levei 1l, the lift rod 9 and the Afiush valve A, in order that when said flush valve 1s vlifted from the valve seat member ol the flush pipe connection, the parts will be evenly balanced and the ilush valve will be approximately evenly balanced and will 'be suplported by resting upon the water in the tan i to descendlagain toward and to its seat as the water escapes from the tank through the flush pipe connection.

14 designates an operating lever to the outer arm of Which a chain or other appliance may be attached for the operation of said lever. The operating lever is pivoted intermediate of its ends to the bracket 13 and it lhas a weighted inner arm 15, provided With` a lug 16 which is located beneath the i inner arm ofthe counterbalance lever 11.

When the outer arm of the operating lever is Alowered the inner Weighted arm of said lcver Ais elevated and acts through the medium of the lug 16 to elevate the innei' arm of the counterbalance lever l1. As a result, thc flush valve A is lifted from its seat and rciiiains in a balanced position in the water that escapes from the tank through the flush pipe connection and fiush pipe. Immediately upon the release ol the operating lever its weighted inner arm descends and the counterbalanee lever serves to sustain the flush valve until the water has escaped from the tank suiiicientl to reach the flush valve,

after which. said ush valve radually descends With the Water to the va ve scatmeniber 3 of the Hush pipe connection.

An -imlportant advantage in my liuslnng tank is t at by the use of a counterbalance lever for the control of the flush valvcl ain' enabled to usea very much more substantial flush valve and connection, such as the lifting rod, therefor than it is ossible to use in thc'abscnce of such counter alance lever.

I claim:

. 1. In a flushing tank, the combination of av lush pipe -connection having a valve seat member, a ioat flush valve, a counterbalance lever having its inner arm connected to said flush valve and its outer arm provided with acounterbalance, and an operating lever v having a Weighted inner arm arranged for' enga ement with the inner arm of said counterba ance lever, substantially as set forth.

2. In a flushing tank, the combination of'ga'- flush pipe connection having a valve seat i arm of said Counterbalance lever, substan- Qmember, a float flush valve, a counterbalance l tially' as set forth.

lever having its inner arm connected to said e I l Hush valve and its outellarm provided With a j I ALLEN R' GILMORE' 5 counterbalence, and an operating larger havf In the presence ofng a Weighted inner arm provlred with a, i LILY POST,

lug arranged for engagement with `he inner i H. G. COOK.
